Question

What is the mean of the first 3001 positive integers?

Answer 1

Answer:

Step-by-step explanation:

Let S = 1 + 2 + 3 + . . . + 3001.

Using the formula Sn =n/2(a+1)

for the sum of the first n terms of an AP, we have

S3001 =3001/2(1+3001)=1500.5 x3002=4504501

So, the sum of the first 3001 positive integers is 4504501
